i saw one of these in australia. it was really small (about a half-inch in diameter) but so fucking pretty. and therefore it bothered me a lot less than the golden orb weaver, which we seemed to see EVERYWHERE and ranged in size from huge to FUCKING MASSIVE.. (totally harmless, i was assured, but it was larger in diameter than my 6'2" dad's hand span.)
ANYWAY. jewel spiders. or, should i say, COOL spiders.
i believe this was the genus i saw in australia?
and that guy's just awesome.
plus, a video of one building a web.
